The session uses a setup with 1024 Mbps and consists of 3 ftp fringe tests, interspersed with a longer set of scans on 3C 345 (~4Jy source at 3mm). For Eb, On20, Nt, Ys, Mh, observation of the SiO maser on RLeo are performed from 08:21:00 UT to 09:23:30 UT. The three ftp fringe-test scans, start at: (1) 08:13:28 UT (scan 2, 2 sec) (2) 09:31:28 UT (scan 10, 2 sec) (3) 10:49:58 UT (scan 18, 2 sec) See you on Skype group chat and Good luck with the session!
